Abstract

PURPOSE: To enable speaking through the hand set of personal handyphone system(PHS) equipment even during high-speed moving by connecting the master unit of the PHS equipment to a car telephone terminal. CONSTITUTION: A base unit 1 to form the PHS equipment together with a hand set 10 inside an automobile 1 is connected to the car telephone terminal. Then, speaking can be performed while using the slave set 10 of the PHS equipment without newly adding any function or circuit to the PHS equipment even during high-speed moving by utilizing the car telephone line of a car telephone antenna 5 or a car telephone base station 60. In this case, when the caller of a telephone call dials the telephone number of the car telephone terminal, a line between the base station 60 and the automobile is secured and the slave set 10 can receive that telephone call.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PHS device, and more particularly to a personal handyphone system that enables high speed movement by using a car telephone terminal.

[0002]

2. Description of the Related Art The conventional device is NIKKEI, Nikkei Inc.
As described in COMMUNICATIONS magazine No. 1994.6.6, it is possible to connect the line between the base unit and the handset as well as the analog cordless phone, direct call between handset, and mobile phone outdoors. There are public service features available to.
Therefore, by always carrying the PHS cordless handset, it is possible to connect the telephone line through the base unit like an analog cordless telephone indoors, and outdoors like a mobile telephone at a walking speed. Can be used Furthermore, it can be used as a transceiver between handset units.

[0003]

The above conventional technique is convenient in that it can be used not only indoors like an analog cordless telephone but also indoors like a mobile telephone. In addition, the output of the terminal is smaller than that of the mobile phone, so that the usage time (standby / continuous call) is long, and the battery capacity is small, so that it is small and lightweight. However, although it can be used at walking speed, it is not possible to make a call while moving at high speed. So personal handyphone system (PH
In S), in order to make a call even while moving at high speed,
It is possible to use a car phone together.

An object of the present invention is to provide a device capable of talking on the PHS even when moving at high speed.

[0005]

According to the present invention, there is provided a master unit of a PHS device interconnected with a car telephone.

[0006]

By adding the function of the car telephone terminal to the parent device of the PHS device, the child device of the PHS device can be used even when moving at high speed.

[0007]

EXAMPLES Examples of the present invention will be described in detail below.

FIG. 1 is an explanatory view of the operation of the PHS device of the present invention, FIG. 2 is a block diagram of the functions of the parent device of the PHS device of the present invention, and FIG. 3 is a perspective view of the PHS device of the present invention.

1 and 3, reference numeral 1 is a main body of the PHS device, 2 is an antenna of the PHS device, 5 is an antenna of a car telephone, 6 is an antenna base, 7 is a coaxial cable, 10
Is a main body of the PHS device, 50 is a moving body, and 60 is a car telephone base station.

The mobile unit 50 is a main unit of the PHS device main unit 1, P.
An HS device master antenna 2 and a car phone antenna 5 are provided.

While the mobile unit 50 is moving at high speed, the PHS device slave unit main body 10 and the PHS base station outside the mobile unit 50 cannot directly connect to the line. However, the moving body 50
Through the PHS device master unit main body 1 having the built-in car telephone terminal function, that is, by using the line of the car telephone, it is possible to talk on the PHS device slave unit main body 10 even when moving at high speed. .

In FIG. 2, 3 is a PHS device master unit circuit,
4 is a car telephone terminal circuit, 31 is a control circuit, 32 is an audio / data processing circuit, 33 is a receiving high frequency amplifier, 3
4 is a receiving frequency converter, 35 is a demodulator, 36 is a voltage controlled oscillator, 37 is a transmitting oscillator / modulator, 38 is a transmitting frequency converter, 39 is a transmitting high frequency amplifier, 41 is a transmitting oscillator /
A modulator, 42 is a transmission frequency converter, 43 is a transmission high frequency amplifier, 44 is a transmission / reception band filter, 45 is a voltage controlled oscillator, 46 is a reception high frequency amplifier, 47 is a reception frequency converter, and 48 is a demodulator.

The PHS device master unit main body 1 comprises a PHS device master unit circuit 3 and a car telephone terminal circuit 4, and includes a PHS device master unit antenna 2 and a car telephone antenna 5.

The PHS device master unit circuit 3 is composed of 31 to 39, and the car telephone terminal circuit 4 is composed of 41 to 48.

Now, in the moving body, the PHS device slave unit main body 10
A signal received by the PHS device master antenna 2 when a call is made from is amplified by the reception high frequency amplifier 33.
After being converted to a desired frequency by the reception frequency converter 34,
Audio data processing circuit 32 demodulated by demodulator 35
When the telephone number data is input to the control circuit 31, the control circuit 31 causes the car telephone terminal circuit 4 to make a call operation, and signals are transmitted by the oscillator / modulator 41, the transmission frequency converter 42, the transmission high frequency amplifier 43, the transmission / reception band. It is transmitted from the car telephone antenna 5 via the filter 44. In addition, car telephone base station 60
The signal from the mobile phone antenna 5 is received by the mobile phone antenna 5 and is input to the audio / data processing circuit 32 via the transmission / reception bandpass filter 44, the reception high frequency amplifier 46, the reception frequency converter 47, and the demodulator 48, and is transmitted to the mobile phone base station 60. Secure a line between. The signal input to the audio / data processing circuit 32 is transmitted from the PHS device master unit antenna 2 to the PHS device slave unit main body 10 via the transmission oscillator / modulator 37, the transmission frequency converter 38, and the transmission high frequency amplifier 39.

When a call is received in the mobile unit, the caller dials the telephone number of the car telephone terminal to secure the line between the mobile unit 50 and the car telephone base station 60.
